Computer won't detect DNS?

Question

Ok, so my computer (a Dell running windows XP) suddenly decided to stop being able to detect DNS yesterday. It connects to the DNS server, but it doesn't get anything back. If I get the IP address of a website from another computer and enter that, then I get the page, but automatic stuff seems to be broken.

Any idea what this is/how to fix it? I've tried purging my DNS cache and the Repair Wireless network button; and all my settings are set to automatic, but still nothing.

OTHER STUFF:
Running: Windows XP Service Pack 3

Browser: Google Chrome (IE doesn't work either though)

Wireless card: D-Link Airplus DWL-G520 wireless PCI Adapter

Answer 1

I agree with the answer suggesting the DNS server you are using is likely down. OpenDNS is an excellent source for reliable DNS.



You can set your computer to use their DNS servers. Since you know how to purge the DNS cache, I am guessing you know where to change this setting. (However, if not, it is in the Internet Protocol section of your Network Adapter's properties).



The open DNS servers are 208.67.222.222 and 208.67.220.220



These can also be configured in your router if you have one.

Answer 2

Without knowing which DNS servers you are using, my simple guess is that they are down. Most ISP's provide DNS information automatically, but if there is an outage, this is the result.



One solution is to use your own DNS. OpenDNS is such a service, and it's free!

Yeah, I would look at your router for starters, does it have lights that show it is broadcasting wireless signal. Can you log into your router via your web browser to check your settings in there? Like SSID is set to broadcast, is your wireless secure with either WEP or WPA-PSK passkey, do you have it set to MAC Address filtering on (which only lets certain recognized MAC address devices jump on), etc... Ahhh..I love the joys of Wi-Fi and wireless routers...When in doubt, read the manual to your router for the web address to log into and check settings. As far as your PC connection: START/ My network places/ view network connections/ click on local area connection/ support. This should list the staus of your internet connection, but not help much with your wireless network, unless you need this for manually entering info. Good luck!
